GAW Report, 227. WMO/GAW Aerosol Measurement Procedures, Guidelines and Recommendations
It is the goal of the Global Atmosphere Watch (GAW) programme to ensure long - term measurements in order to detect trends in global distributions of chemical constituents in air and the reasons for them (WMO, 2001a). With respect to aerosols, the objective of GAW is to determine the spatio - temporal distribution of aerosol properties related to climate forcing and air quality on multi - decadal time scales and on regional, hemispheric and global spatial scales. The objective of GAW Report No. 153, published in 2003, was to provide a synthesis of methodologies and procedures for measuring the ...

It is the goal of the Global Atmosphere Watch (GAW) programme to ensure long - term measurements in order to detect trends in global distributions of chemical constituents in air and the reasons for them (WMO, 2001a). With respect to aerosols, the objective of GAW is to determine the spatio - temporal distribution of aerosol properties related to climate forcing and air quality on multi - decadal time scales and on regional, hemispheric and global spatial scales. The objective of GAW Report No. 153, published in 2003, was to provide a synthesis of methodologies and procedures for measuring the recommended aerosol variables within the GAW network. The report has been extensively used by the scientific community, and more particularly by scientists and engineers involved with data production from ground - based sites. The knowledge of aerosol impact on climate and air quality as well as the techniques used for the determination of the essential aerosol variables to be monitored at ground - based sites have considerably evolved in the last decade, justifying an update of GAW Report No. 153. This update has been prepared shortly after the release of the Working Group 1 report from the International Panel on Climate Change (IPCC, 2013). A clear emphasis was given for the first time in IPCC reports since 1992 to the analyses of evidence of climate change from observations of the atmosphere highlighting the challenges for d eveloping long - term, high quality observation record that can be used to constrain models at global and regional scales. While the benefit of improved monitoring capabilities developed in the last decades, both from satellites and ground - based has been cl early assessed for the production of more reliable data records, the report still highlights the need for maintaining and enhancing the capacity of the observing system to provide the additional constrains, in particular for the derivation of trends.

SatFC-G: Near-IR Bands
This lesson introduces you to three of the four near-infrared imager bands (at 1.37, 1.6, and 2.2 micrometers) on the GOES R-U ABI (Advanced Baseline Imager), focusing on their spectral characteristics and how they affect what each band observes. For information on the 0.86 micrometer near-IR "veggie" band which is not included here, refer to the Visible and Near-IR Bands lesson. This lesson is a part of the NWS Satellite Foundation GOES-R Course.

SatFC-G: IR Bands, Excluding Water Vapor
This lesson introduces seven of the ten infrared imager bands on the GOES R-U ABI (Advanced Baseline Imager). It examines the spectral characteristics of each band to facilitate a better understanding of band selection and what each band observes, and to shed light on some of the many potential applications. This lesson is a part of the NWS Satellite Foundation GOES-R Course.Permalink![]()

Analysis of aerosol optical depth (AOD) retrieved from light detection and ranging (LIDAR) and sunphotometer measurements
Aerosols are small, micrometer-sized particles, whose optical effects coupled with their impact on cloud properties is a source of large uncertainty in climate models. Aerosols when inhaled are believed to have significant and detrimental effects on human health. Their presence also affects photosynthesis and agricultural production. Aerosol measurements are urgently required for the complete understanding and modeling their role in the climate system. This study builds on the analysis of Aerosol Optical depth (AOD) using Light Detection and Ranging (LIDAR) and sun photometer measurements then ...Permalink![]()
Aerosol Measurement by Raman Lidar
This paper examines the aerosol extinction coefficient profiles measured by Rayleigh-Raman-Mie-Lidar (RRML) system in Nanjing, China. I introduced two lidars methods (Raman and Fernald) and detection principle, and two lidars data Using Raman analysis method and Fernald analysis method to obtained aerosol extinction coefficient. Aerosol profiles at 607 nm and 532 nm over ranges from 6 km to 10 km were obtained using respectively Raman lidar and Rayleigh lidar in Nanjing.PermalinkPermalinkPermalinkPermalink![]()

Investigating apparent aerosol effects on precipitation in climate model simulations
Aerosols in the atmosphere serve as condensation nuclei for the cloud formation. This brings an important influence on the microphysical properties of cloud water that in turn affect the processes in the formation of precipitation. Aerosol-cloud-precipitation interaction which simultaneously change cloud albedo interest many studies to find out aerosol impact on precipitation formation. The studies were done by observation measurement and simulation. UK Met Office Unified Model (UM) is one model that includes aerosol direct and indirect effect in the NWP configuration which leads to study aero ...Permalink![]()
GOES-R ABI: Next Generation Satellite Imaging
This extension of the COMET lesson “GOES-R: Benefits of Next Generation Environmental Monitoring” focuses on the ABI instrument, the satellite's 16-channel imager. With increased spectral coverage, greater spatial resolution, more frequent imaging, and improved image pixel geolocation and radiometric performance, the ABI will bring significant advancements to forecasting, numerical weather prediction, and climate and environmental monitoring. The first part of the lesson introduces the ABI's key features and improvements over earlier GOES imagers. The second section lets users interactively ex ...Permalink
